Item Description

Siglo XX is one of the most impressive Bolivian localities hands down. It is the type locality for many "best in the world" species, and it even produces some amazing specimens of common species like Quartz. Japan-Law twin Quartz specimens are well known in the mineral world, and this piece is a great example of said material. The specimen hosts several absolutely water-clear, razor sharp, highly lustrous, prismatic, colorless Quartz crystals, which are associated with white to grey colored, velvety, botryoidal Wavellite, but the most important apsect of the piece is a few attractive Japan-Law twins measuring up to 3.5 cm across which can be found throughout the specimen.. I've drawn a few red lines on the photos to actually show the defnition of some of twins the better, as the piece is very three-dmiensional and it's hard to see among the other crystals in a two-dimensional photo. The piece is very eye-catching and superb quality for the material. It is certainly one of the best I have offered in a long time. Hand-sized display specimens of Japan-Law twin Quartzes from Siglo XX are simply not seen on the market anymore. Priced at $950 in my inventory. Enjoy!
